Arctica takes the next step in facilitating responsive web design in Drupal. It works in the background, providing Drupal with a layout system via the Skinr module and its own CSS management system. But unlike other base themes it doesn’t stop there; The Arctica Configurator (aka theme settings form) provides an entirely new interface that reduces the complexity of responsive design by showing and telling what is happening in the background, when your website is elegantly adapting to and infinite number of screen sizes.

This module integrates the Responsive Images library created by Filament Group.The purpose of this library is to load images in different sizes based uponthe resolution of the browser loading the page. This allows for mobile-optimized images.This module provides a "Responsive Images" image field formatter for which you can selectboth a small (mobile-optimized) image style as well as a large (for normal screens) image style.
